MACHINE FOR WEAVING COlLED-WIRE FABRIC.

SPECIFICATION forming part of Letters Patent No. 464,940, dated December 8,1891.

Application filed April 16,1891.

To all whom it may concern:

Be it known that I, CYRUS KEHR, a citizen of the United States, residing at Lakeside, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for \Veaving Coiled-Wire Fabric; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and-use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates, particularly, to the weaving of coiled-wire fabric for bed-bottoms and similar purposes, such fabric consisting of parallel longitudinal interlinked spiral wire coils. r

One of the objects of my invention is to provide sufficient mechanism for holding the edge of the fabric to which the new coils are being applied and to receive and guide the coils as they are being projected from the coil-forming mechanism. The portion of the mechanism by which this object is attained is adapted to use in machines embodying only one or more than one coiler.

My improvement relates also to certain details of construction, as will hereinafter appear.

In this class of machines the wire is coiled anism has been heretofore devised, and it is therefore deemed unnecessary to describe such mechanism at length.

In the accompanying drawings, Figure 1 is a plan. Fig. 2 is a side elevation. Fig. 3 is a vertical trai'isverse section in line a I), looking to the left inFig. 1. Fig. at is a vertical section in line a I), looking to the right in Fig. 1. Figs. 5 and 6 are detail views of the mechanism for holding the edge of the fabric and receiving the new coils. Figs. 7, 8, and 9 are details of the coil-forming mechanism. Fig. 10 is a diagram illustrating the timing of the cams which control the coil-forming mechanism, the knives, and the movement of the fabric-holding mechanism. Fig. 11. is'a sec- Serial No. 389,173. (No model.)

tion in linea c of Fig. 1. Fig. 12 shows a modified coil-receiving mechanism.

A is a table rising to a suitable height and of proper width and length to supportthe operating mechanism. The portion of the table at the right in Figs. 1 and 2 is called the head of the table and the portion at the left in said figures is called the foot of the table and the corresponding ends are also called the head and foot of the machine. The machine may embody only one coiler, but the drawings illustrate two.

B is a coiler located at the head of the machine, and C is a coiler located at the footof the machine. Both are located upon the table and are in the same plane and have their coiling-axes parallel to each other and separated a little less than the diameter of one coil, so that the coils simultaneously projected'from these coilers will intertwine and have theiraxes separated. These coilers may be of any suitable construction. The drawings show them both composed of similar parts, and a description of the coiler B will therefore be sufficient for both.

13 is a spindle lying between blocks B and E the former resting upon the table and the latter being clamped upon said spindle by bolts 13", located in an arched standard B", rising from the table A. At the right there is an opening B of proper size to allow the passage-of the wire D, and said passage leads to the spindle B and thence spirally forward around the latter. A pair of rolls B are arranged at the head of the coder and. geared to feedthe wire forward into the passage B F and F are band-wheels seated upon a shaft F extending longitudinally beneath the table A, the wheel F being keyed to said shaft and the wheel F being loose thereon. YVhen a belt is placed upon the wheel F, the shaft F is rotated continuously, and when it is desired to stop the rotation of said shaft the belt is shifted to the loose wheel F. F is a clutch surrounding said shaft F and feathered thereon, so that it may be shifted longitudinally, but must rotate with the shaft F F is a bevel-gear loosely surrounding said shaft F but designed to be at times engaged with the clutch F and during such engagewheel F fixed upon the shaft of one of the rolls B. By this train of mechanism the rolls are driven so as to feed the wire D forward through the coiler B. A similar train of mechanism is located at the foot of the machine and similarly connected with the shaft F to drive the coiler (J.

The clutches F may be shifted into and out of engagement by means of bell-cranks G and a cam H, located upon the shaft F The vertical arm of each of said bell-cranks engages one of the clutches, and the horizontal arms approach each other and rest over the cam H, the elbow of said cranks being pivoted'to the table A. The meeting ends of the horizontal arms of the bell-cranks are preferably united, so that they and the clutches controlled by them must move in unison as the extended portion H of the cam H passes beneath said meeting ends. A coiled spring G is joined by one end to one of said arms and by the other end to the shaft F or some other relatively fixed object, and serves tohold the meeting ends of the bellcranks normally down in. contact with the cam H, so that the clutches F are normally in engagement with the wheels F The raisingof the meeting ends of said horizontal arms of the bell-cranks draws the vertical,

arms of said bell-cranks toward the middle of the machine, so that said clutches are drawn away from and out of engagement with the bevel-wheel F whereby the train of mechanism concerned in driving the coiler is stopped. Said train of mechanism is so speeded that one coil is formed by the coiler for each rotation of the shaft F less a portion of said rotation covered by the interval required for cutting the wire and shifting the fabric. shown as covering about one-tenth of the periphery of the cam H, and when this proportion exists the coil must be formed during a nine-tenths rotation of the shaft F .When the machine is thusstopped, the wire is to be cut and the fabric shifted transversely to the coiling-axis before the coilers are again started. Both of these steps may be performed byhand or by mechanism operated by hand; but I have devised automatic mechanism for this purpose, which mechanism is arranged in such relation to the shaft F as to be actuated by the latter at suitable intervals.

I and J are endless aprons, each stretched upon a pair of horizontal parallel shafts and meeting in the plane in which lie the coilingaxes of the coilers B and O. The meeting faces of these aprons are of such construction that they will together form. passages for the coils of the fabric. I

I is the lower apron, and I is the apron-sup- In Fig. 3 the extension H is.

directly upon said shafts, the latter being then of considerable diameter; but I show them as resting upon sprocket-wheels I I and J J the aprons being composed, respectively, of sprocket chains I and J surrounding the said sprocket -wheels, and longitudinally-channeled strips 1 and J, secured to said sprocket-chains. It will be understood that in lieu of the sprocket-chains other chains or endless and jointless metallic bands may be used, the wheels I I and J J being then provided with smooth peripheries. The strips I and J 6 may be of suflicient width to cover the width of several coils d of the fabric D, and thechanneling for one coil is to extend into the channeling for the adjacent coils, in order that each coil may reach into th'espace occu pied by the coilat each side and interlink with the latter. The coilers are shown arranged to project coils into the space between the aprons I and J to the front of the machine, as shown in Figs. 1 and 2, and at the left, as shown in Figs. 3 and 5. 1

In operation acoil is projected from one of the coilers into one of the spaces between the aprons and another coil is projected into one of the adjoining spaces and intertwined with the first-mentioned coil. Thecoilers are then stopped and. the wire cut between, the coilers and the aprons. The aprons are then simultaneously progressed in the direction inditwining with the forward of the two previously-made coils. The aprons are then again made to progress ,in the direction indicated by the arrows in Fig. 5, so that two-vacant spaces are again formed, and the forming of two coils is again repeated, and so on indefinitely, the fabric finally issuing from between the aprons at the rear of the machine, as shown in said Fig. 5. It will be seen thatin this manner the edge of the fabric to which the new coils are being applied is positively held, and the coils being formed are provided with definite paths, so that they must intertwine with the last-finished coils of the fabric and with each other.

In order that the two aprons may travel in unison two of the shafts, as Iand J, are each provided with a spur-gear S and S, one meshing into the other. The said aprons may be progressed in several ways; but it is manifestlypreferable to cause their progression by automatic means. The drawings show for this purpose a ratchet mechanism actuated from the power-shaft F I is a ratchet-wheel located -upon the head end of the shaft I with teeth directed away from the direction of rotation necessary to rotate the aprons, as indicated by the arrows.

I is a rock-shaft supported horizontally beneath the table A and having at one end the dog 1 engaging the teeth of the ratchet-wheel 1 and having-at the other end an arm 1 ex tending to a cam I, located upon the shaft F and having an extension 1 lVhen said extension 1 passes beneath the arm 1 the free end of the latter is raised, the rock-shaft I and the dog I thrown forward, so as to turn the wheel 1 shaft 1 and the aprons I and J sufficiently to move two coilspaces out of the coiling-axes and bring two more coil-spaces into the coiling-axes. An expanding spring 2' may be inserted between the table A and said arm I in order to hold the latter nor mally in its depressed position.

L is a knife supported immovably close to the path of the forming-coil at each end of the aprons, and L isa movable knife arranged in opposition to the knife L at the side of the wire'of the forming-coil opposite the knife L. In other words, the wire of the forming-coil passes between said knives. Said knives may be operated manually or mechanically by different means; but the drawings show an arrangement for operating them simultaneously from a single cam located upon the shaft F L is a shaft extending lengthwise of the machine and parallel to the coiling-axes and journaled in bearings L and supporting at its ends the knives L. At the middle of said shaft L an arm L extends from said shaft to the cam L located upon the shaft F and has an extension L \Vhen said extension passes beneath said arm, it raises the latter, tilts the shaft I1 and presses the free ends of theknives L down on the wire of the coils, so that. the latteris out. An expanding coiled spring Z may be located between the table A and the arm L to hold said arm normally against its cam.

The modification shown in Fig. 12 comprises the coil-receiving mechanism consisting of one endless apron and a roller R, bearing against said endless apron, a surface of the roller and of theendless apron being arranged to form spaces between the meeting faces of said roller and said apron. It will be seen that the roller and the apron are each a movable part of the mechanism characterized by having an endless surface, and whether two endless aprons or one endless apron and a roller are used there are combined an endless apron and a movable part having an endless surface.
